EXAMPLE: 100/23 = 4, remainder 8
By using a calculator:)
To convert a remainder into a fraction, you can simply place the remainder over the divisor. For example, if you have a remainder of 2 when dividing 7 by 3, you can express it as 2/3. To convert the remainder into a decimal, divide the remainder by the divisor. In the same example, dividing 2 by 3 would give you 0.666... or 0.67 when rounded to two decimal places.

No. The part of the number after the decimal point (if any) is the quotient of the remainder from the original division and the original denominator.
The only way, without a calculator, that I know of is long division.
Why do you need a calculator?
Just do the division, and if there is a remainder - or a decimal, if you use the calculator - it is not divisible.
Divide 74 by 9 on a calculator. If there's nothing after the decimal point, then there's no remainder, which means it does. If there is a remainder, it does not.
By using a calculator:)
divide it and multiply it with some numbr
Divide it by the divisor (the denominator).
you divide the numerator by the denominator
All remainders on a calculator will appear as a decimal. Some TI scientific calculators can convert the answer into a fraction.
numerator (top) divided by the denominator (bottom)
Punch in 5 divided by 9 in your calculator.
